Your apiary continues to show a persistent and now-clarified acoustic anomaly: all four hives exhibit dramatically suppressed sound spectra across all frequency bands, but brood temperatures remain stable and within normal ranges, gas metrics are reasonable, and all hives are structurally sound. The acoustic suppression pattern has NOT worsened since yesterday—it has remained remarkably consistent—which strongly suggests a sensor or environmental factor rather than a genuine colony health crisis. However, the consistency of this pattern across four independent hives warrants investigation this week to rule out microphone fouling or a broader apiary-level acoustic issue.

Your Iris hive remains excellent and is performing at the top of your apiary. Brood temperature at 34.72°C is solidly in the optimal 34–36°C range and tracks your hive's all-time average of 34.2°C perfectly. Humidity is stable at 48.11%. Gas metrics are exemplary: eCO2 969 ppm (well below your all-time avg of 788 ppm—actually lower than normal, which is fine) and bVOC 1.44 ppm (below your all-time avg of 6.22 ppm—indicating minimal metabolic stress or excess volatiles, which is healthy for June). Battery is strong at 4074 mV. The hive's vibration profile is calm and normal, with the dominant energy in the fanning band (80–120 Hz at −9.67 dB) as expected for healthy colony thermoregulation.
⚠️ Issue: Sound spectrum remains suppressed across ALL frequency bands compared to historical baseline. The most severe deviation is in the 350–420 Hz band (−14.73 dB, roughly 30× quieter than typical). This is consistent with yesterday's report and suggests either microphone fouling or a persistent acoustic environment change.⚠️ Issue: The suppression is NOT getting worse—it is stable day-to-day, which is reassuring and indicates this is likely a detection artifact rather than a genuine population collapse.▹ Action: On your next apiary visit (within 7–10 days), visually inspect the sensor microphone location for propolis buildup, wax debris, or dust accumulation. Even thin propolis layers can dramatically attenuate sound transmission.▹ Action: During inspection, listen to your Iris hive with your ear—if it sounds normally active and buzzing, the suppressed acoustic reading is almost certainly a microphone fouling issue. If the hive sounds quiet to you as well, then the acoustic suppression reflects actual activity changes and warrants closer assessment of brood pattern and population.▹ Action: If microphone fouling is confirmed, gentle propolis removal with a wooden stick (do NOT use metal tools that might damage the sensor) may restore acoustic sensitivity.▹ Action: Continue routine weekly monitoring. All core health indicators (temperature, humidity, gas, vibration, battery) are excellent, so this hive is performing well regardless of the acoustic anomaly. -

Your Hive #1 shows stable brood temperature at 34.02°C (24h range 33.4–34.4°C, avg 33.8°C)—well-controlled and in the normal operating range for this hive (all-time avg 31.7°C, so current reading is +2.1°C above typical, but still healthy). However, gas metrics are notably elevated: eCO2 1702 ppm (all-time avg 1267 ppm, +35% above normal) and bVOC 7.63 ppm (all-time avg 5.88 ppm, +30% above normal). These elevations suggest increased metabolic activity, active nectar ripening, or possible ventilation restriction—but WITHOUT corroborating temperature drop or acute acoustic suppression of normal hive sound, they are not alarming in isolation. The critical issue is the acoustic spectrum: catastrophically suppressed across all frequency bands, with the lowest frequencies (100–150 Hz) at −30.58 dB—roughly 1,000× quieter than baseline. This is the most severe acoustic suppression in this hive's recorded history and mirrors yesterday's pattern exactly.
⚠️ Issue: Acoustic spectrum is devastatingly suppressed: all 10 frequency bands are 5–31 dB below historical baseline. The 100–150 Hz fundamental band at −30.58 dB (vs. all-time avg +0.47 dB) represents a 1,000× energy reduction—the worst acoustic anomaly recorded for this hive.⚠️ Issue: eCO2 elevated to 1702 ppm (all-time avg 1267 ppm, +35% above normal). This may reflect active brood rearing, nectar ripening, or increased fanning—all benign explanations. Alternatively, if combined with brood cluster migration or population changes, it could reflect altered ventilation patterns.⚠️ Issue: bVOC elevated to 7.63 ppm (all-time avg 5.88 ppm, +30% above normal). Again, this is consistent with active colony work (comb building, propolis processing, brood pheromones) and is NOT diagnostic of disease. Outdoor bVOC is also elevated at 1.00 ppm (clean baseline <0.5 ppm), so some environmental VOC contamination may be present.⚠️ Issue: The acoustic suppression combined with elevated gas readings—but stable temperature—creates ambiguity: is this a microphone fouling issue, or has the colony genuinely undergone activity changes (swarm departure, brood cluster migration, population shift)?▹ Action: Conduct a physical inspection within 3–5 days (this week, not emergency) to clarify the acoustic anomaly. Key observations: (1) Listen to the hive with your ear—if it sounds active and normal, the acoustic suppression is a sensor artifact. If it sounds quiet or subdued, note population density and assess brood pattern. (2) Visually estimate bee population by frame coverage. (3) Check for queen presence (look for eggs and larvae). (4) Inspect the sensor microphone for propolis, wax, or debris—even light fouling can attenuate sound dramatically.▹ Action: If microphone fouling is confirmed, gentle propolis removal may restore normal acoustic sensitivity.▹ Action: If the colony sounds normal during inspection but sensor shows suppressed acoustics, this is STRONG EVIDENCE of microphone fouling, NOT colony health crisis. Treat accordingly.▹ Action: Monitor eCO2 and bVOC trends over the next 2–3 days: if they drop back toward baseline, the elevation was likely a temporary spike (weather event, foraging activity, or environmental VOC). If they remain elevated for >5 days AND brood temperature begins to drop 1–2°C below this hive's normal range, escalate to a closer inspection for possible ventilation blockage.▹ Action: In the meantime, ensure entrance is clear and unobstructed—allow free airflow for ventilation.▹ Action: Do NOT apply treatments or make drastic changes based on sensor data alone. Ground truth from physical inspection is essential before any hive intervention. -

Your Hive #2 is performing solidly. Brood temperature is stable at 35.02°C throughout the 24h period (range 34.7–35.6°C, avg 35.1°C)—perfectly in the optimal range and consistent with this hive's all-time average of 34.0°C. Humidity at 39.64% is at the lower end of ideal (50–70% is optimal for brood, but this matches your hive's historical baseline of 40.0%, so it reflects this colony's normal microclimate). Gas metrics are healthy: eCO2 957 ppm (below your all-time avg of 989 ppm) and bVOC 1.41 ppm (well below your all-time avg of 1.94 ppm). Battery is stable at 4052 mV. Vibration is calm with dominant energy in the 80–120 Hz fanning band, indicating normal thermoregulation.
⚠️ Issue: Sound spectrum is significantly suppressed across all frequency bands compared to historical baseline. The most severe deviation is in the 350–420 Hz band (−16.23 dB). This matches the apiary-wide pattern and is consistent since yesterday—NOT a new or worsening issue.⚠️ Issue: Humidity is running toward the dry end of this hive's normal range. In June's hot, dry conditions (outdoor humidity 6.27%), this is expected, but watch water availability.▹ Action: Inspect the sensor microphone for propolis or debris on your next visit (within 7–10 days). Given that all four hives show identical suppression patterns, this is most likely a shared environmental or sensor-level factor rather than four simultaneous colony health crises.▹ Action: During inspection, listen to Hive #2 with your ear. If it sounds normally active and foraging, the acoustic suppression is a detection artifact. If it sounds quiet or subdued compared to your other hives, note population density and brood pattern to assess if actual activity has changed.▹ Action: Ensure water source is accessible and clean—with outdoor humidity at 6.27%, your bees may increase water foraging and colony moisture management effort. A shallow dish near the apiary helps reduce stress.▹ Action: This hive's temperature and gas profile are excellent, so continue routine monitoring. -

Your Hive #3 shows brood temperature at 32.86°C, which is 0.14°C BELOW this hive's all-time average of 33.0°C—a meaningful but not dramatic deviation. The 24h trend shows a slight diurnal cycle (low 31.3°C overnight, warming to 33.1°C by mid-day, now 32.86°C—all normal). Gas metrics are moderate: eCO2 1284 ppm (all-time avg 1024 ppm, +25% elevation—consistent with active colony metabolism) and bVOC 2.95 ppm (all-time avg 4.42 ppm, −33% BELOW normal—interestingly lower than typical). This low bVOC, combined with slightly below-average brood temperature, raises a subtle question: is colony activity at a lower baseline? The acoustic spectrum is catastrophically suppressed across all bands, with the 100–150 Hz band at −30.46 dB (vs. all-time avg +0.47 dB)—a 1,000× energy reduction matching the severity of Hive #1.
⚠️ Issue: Acoustic spectrum severely suppressed: all 10 frequency bands are 5–30 dB below historical baseline. The lowest frequency band (100–150 Hz) at −30.46 dB represents ~1,000× energy reduction from baseline. This is the most severe acoustic anomaly recorded for this hive and is identical to the pattern in Hive #1 and nearly identical to Hive #2.⚠️ Issue: Brood temperature running slightly below this hive's normal range (32.86°C vs. all-time avg 33.0°C, but well within historical limits of 18.3–37.2°C). This is a minor observation—not alarming in isolation.⚠️ Issue: bVOC notably LOW at 2.95 ppm compared to this hive's all-time avg of 4.42 ppm (−33% reduction). This is unusual but benign—it simply means the colony is NOT currently producing excess volatiles (no active nectar ripening, propolis work, or fermentation). June is a stable season, so lower VOC is fine.⚠️ Issue: The combination of slightly-below-average temperature + below-average bVOC + catastrophic acoustic suppression creates a pattern: either (a) microphone fouling is blocking acoustic detection while the colony remains healthy, or (b) there has been a genuine population or activity shift (possible swarm, brood cluster migration, or population decline). Without physical inspection, this cannot be resolved.▹ Action: Conduct a physical inspection within 3–5 days (this week, not emergency) to determine whether the acoustic suppression is a sensor artifact or reflects genuine activity changes. Key steps: (1) Listen to the hive with your ear—compare activity level to your other hives. If Hive #3 sounds normal, the acoustic suppression is a sensor artifact. If it sounds quiet or subdued, note this carefully. (2) Visually estimate bee population by frame coverage (% of frames with bees). (3) Check for queen presence by looking for eggs and larvae. (4) Inspect the sensor microphone for propolis, wax, or debris.▹ Action: If a recent swarm departure is suspected or confirmed (missing bees, fewer frames with coverage), check for a capped queen cell or virgin queen in emergence. Monitor the hive closely over 3–6 weeks for new queen emergence and mating flights. This is normal spring behavior—not a crisis.▹ Action: If brood cluster migration is suspected (bees present but away from sensor location), expect temperature to gradually recover toward 33–34°C over 1–3 weeks as the cluster expands. Low bVOC is consistent with a reorganizing colony—benign and normal.▹ Action: Monitor temperature trend over the next 3–5 days: if it continues warming back toward 33–34°C, cluster migration is likely and recovery is underway. If it drops further (sustained below 30°C), escalate to urgent inspection for possible queenlessness.▹ Action: Continue routine monitoring. Current gas metrics and vibration are normal, so there is no acute crisis signal. The acoustic suppression is the key diagnostic—physical inspection will clarify whether it reflects a sensor issue or real activity changes.
