Your apiary shows a consistent acoustic anomaly across all four hives—dramatically suppressed sound spectra that persists from yesterday's report. This is the primary concern warranting investigation. However, brood temperatures remain stable and within or near normal ranges, gas metrics are reasonable, and all hives are upright with healthy batteries. The acoustic suppression is most likely a sensor-level or environmental factor (propolis fouling, microphone debris, or atmospheric conditions) rather than colony collapse. A physical inspection this week to assess sensor cleanliness and confirm brood patterns will clarify whether this is a detection artifact or a genuine population change.

Your Iris hive remains your apiary's strongest performer. Brood temperature sits at 34.23°C—solidly in the optimal 34–36°C range and consistent with this hive's all-time average of 34.2°C. Humidity at 48.79% is healthy. Gas metrics are excellent: eCO2 721 ppm and bVOC 0.82 ppm, both well below this hive's all-time averages. The sound spectrum continues to show the expected dominant energy in the 1500–3600 Hz fanning band (9.0 dB), though the lower frequency bands remain muted compared to historical norms. Battery is stable at 4066 mV. Vibration profile is calm and normal.
⚠️ Issue: Sound spectrum remains suppressed across lower frequency bands (100–150 Hz: −16.0 dB, historical avg −0.1 dB)—a 100× reduction in low-frequency energy. This mirrors yesterday's report and suggests either microphone fouling or an acoustic environment change specific to this hive's sensor placement.▹ Action: Continue routine weekly monitoring—this hive's core health indicators (temperature, humidity, gas, battery, vibration) are all excellent.▹ Action: On your next inspection (within 7–10 days), visually inspect the sensor location for propolis buildup or debris around the microphone opening. Gentle propolis removal may restore acoustic sensitivity if fouling is the cause.▹ Action: Compare this hive's sound profile to your notes: if the hive sounds normal during inspection (audible buzzing, foraging activity) but the sensor shows suppressed acoustics, sensor fouling is the likely culprit.▹ Action: Maintain water access during June's hot, dry conditions (outdoor humidity 6.67%). -

Your Hive #1 shows stable brood temperature at 33.83°C, which is within normal operating range for this hive (all-time avg 31.7°C, recent 24h avg 33.8°C). Humidity is moderate at 42.14%. However, gas metrics are notably elevated for this hive: eCO2 1719 ppm (well above this hive's all-time avg of 1267 ppm, +36% elevation) and bVOC 7.94 ppm (above all-time avg of 5.88 ppm, +35% elevation). These readings suggest elevated metabolic activity or ventilation restriction, but without corroborating temperature drop or acoustic population signals, the elevation is not yet alarming. The most striking issue is the acoustic spectrum: catastrophically suppressed across all frequency bands (max deviation −30.6 dB in 100–150 Hz—a 1,000× energy reduction). This is the most severe acoustic suppression in this hive's recorded history.
⚠️ Issue: Acoustic spectrum is devastatingly suppressed: all 10 frequency bands are 5–30 dB below historical baseline. The 100–150 Hz band is −30.1 dB (all-time avg 0.47 dB)—roughly 1,000× quieter than expected.⚠️ Issue: eCO2 elevated to 1719 ppm (all-time avg 1267 ppm, +36%). This may reflect increased colony metabolism during active brood rearing, or it could indicate ventilation restriction.⚠️ Issue: bVOC elevated to 7.94 ppm (all-time avg 5.88 ppm, +35%). Combined with elevated eCO2, this suggests either active nectar ripening / comb building or a more stagnant hive environment. Outdoor bVOC is also elevated (1.14 ppm), so some environmental contamination may be present.⚠️ Issue: The apiary-wide acoustic suppression affecting Hive #1, Hive #2, and Hive #3 suggests either (a) multiple microphones fouled simultaneously (less likely); (b) an environmental acoustic factor (atmospheric conditions, sensor firmware); or (c) multiple colonies experiencing genuine population or acoustic changes.▹ Action: Conduct a physical inspection within 3–5 days (not urgent, but worth a closer look this week) to: (1) assess bee population density visually; (2) check for queen presence (look for eggs, larvae, capped brood); (3) inspect the sensor microphone for propolis, wax, or debris; (4) note overall hive organization and entrance activity.▹ Action: During inspection, if the colony sounds and behaves normally but sensor shows suppressed acoustics, suspect microphone fouling. If the colony is visually quiet or disorganized, the acoustic suppression may reflect actual population or brood-rearing changes—monitor the colony closely over the next 2–3 weeks.▹ Action: Monitor eCO2 and bVOC over the next 2–3 days: if they drop back toward baseline, the elevation was likely a temporary spike (weather, foraging activity, or environmental VOC event). If they remain elevated AND temperature remains stable AND sound remains suppressed, this warrants investigation for possible ventilation issues or fermentation.▹ Action: Ensure good entrance airflow and no blockages that might restrict ventilation.▹ Action: Continue monitoring temperature and gas trends; if temperature begins to drop 1–2°C below this hive's normal range while sound remains suppressed, prepare for a more urgent inspection to assess queen status. -

Your Hive #2 is performing well overall. Brood temperature at 34.91°C is in the optimal range and stable throughout the 24h period (34.9–35.6°C avg 35.2°C). Humidity is moderate at 40.01%—lower than ideal for optimal brood rearing (50–70%) but consistent with this hive's historical baseline of 40.0% avg, so it is normal for this colony's microclimate. Gas metrics remain reasonable: eCO2 824 ppm and bVOC 1.04 ppm, both well-controlled. Battery is healthy at 4074 mV, vibration is calm, and tilt is normal at 8°.
⚠️ Issue: Acoustic spectrum is significantly suppressed across most frequency bands compared to historical baseline (max deviation −16.1 dB in 350–420 Hz band). This matches the pattern seen in all four hives and suggests an apiary-wide acoustic factor rather than a hive-specific colony health problem.⚠️ Issue: Humidity is at the lower end of this hive's range (40.0% vs. historical avg 40.0%), which is fine for this colony's normal operating point, but keep an eye on it in hot, dry weather—bees may work harder to manage moisture balance.▹ Action: This hive's temperature and gas profiles suggest strong health. On your next inspection (within 7–10 days), visually assess the sensor microphone for propolis fouling and confirm brood pattern.▹ Action: The suppressed acoustics are consistent with all other hives, so focus on (a) microphone cleanliness and (b) confirming that actual bee population and activity levels are normal during the inspection.▹ Action: Ensure adequate water access during hot, dry weather. -

Your Hive #3 shows brood temperature at 32.62°C, which is 0.4°C below this hive's all-time average (33.0°C) but within the normal historical range. However, the 24h temperature trend shows a notable dip: overnight low of 29.6°C, now warming toward 32.7°C—a 3.1°C rise this morning. This is normal diurnal warming and not alarming. Gas metrics are moderate: eCO2 1124 ppm (all-time avg 1024 ppm, +10%) and bVOC 2.05 ppm (all-time avg 4.42 ppm, −54% below normal—actually lower than typical for this hive). Humidity is at 40.88%. The critical concern is the acoustic spectrum: catastrophically suppressed across all frequency bands, matching the severity seen in Hive #1 (max deviation −30.7 dB in 100–150 Hz—roughly 1,000× quieter than baseline).
⚠️ Issue: Acoustic spectrum severely suppressed: all 10 frequency bands are 5–30 dB below historical baseline, with the lowest frequency band (100–150 Hz) showing −30.2 dB vs. all-time avg 0.47 dB. This represents a 1,000× energy reduction and is the most severe acoustic anomaly in this hive's recorded history.⚠️ Issue: Temperature is running 1.5°C below all-time average (31.5°C 24h avg vs. 33.0°C all-time avg). This is a meaningful but not dramatic deviation—well within the historical range (min 18.3°C, max 37.2°C).⚠️ Issue: bVOC is notably LOW at 2.05 ppm compared to this hive's all-time avg of 4.42 ppm (−54% reduction). This is unusual and may suggest either lower colony metabolic activity or cleaner air conditions. Outdoor bVOC is elevated (1.14 ppm), so the hive's lower reading suggests the colony is NOT actively producing VOCs.⚠️ Issue: The multi-hive acoustic suppression combined with Hive #3's below-average temperature raises a question: has there been a genuine population change (e.g., swarm departure, or brood cluster migration), or is this a sensor artifact? The combination of acoustic + temperature signals warrants investigation.▹ Action: Conduct a physical inspection within 3–5 days to: (1) confirm queen presence and assess brood pattern (eggs, larvae, capped brood); (2) estimate bee population density by visual inspection of frame coverage; (3) check the sensor microphone for propolis or debris; (4) assess overall hive organization and entrance activity.▹ Action: CRITICAL DIAGNOSTIC: During inspection, listen to the hive with your ear. If the hive sounds quiet/subdued compared to your other colonies, the acoustic suppression is real and may reflect actual population loss (possible swarm, or brood cluster migration). If the hive sounds normal to you but the sensor shows suppressed acoustics, suspect microphone fouling.▹ Action: If a recent swarm departure is confirmed (or suspected), check for a capped queen cell or emerging virgin queen. Monitor the hive over the next 3–6 weeks for new queen emergence and mating.▹ Action: If brood cluster migration is suspected (bees moved brood away from sensor location), expect temperature to gradually recover toward this hive's normal 33–34°C range over 1–3 weeks as the cluster re-expands. This is normal spring behavior.▹ Action: Monitor temperature trend over the next few days: if it continues to rise back toward 33–34°C, the low reading is likely a temporary cluster position issue. If it drops further (below 30°C sustained), this suggests population loss or queenlessness—inspect urgently.▹ Action: Low bVOC is benign—it simply means the hive is not currently producing excess volatiles (no active nectar ripening, propolis work, or fermentation). This is fine in June.
